WINDOW GUARD.

Application led June 8,

My invention relates to an improvement in window guards and has for its object to provide a guard operable independently ot the window sash and adapted to be so mounted as to be normally concealed, there being key controlled means to loclitiin one or more operating positions.

It is a further distinctive feature or my invention that by arranging a guard of this type in the guides for the upper or outer sa sh it is adapted when locked in position not only to serve as a guard for the lower sash opening but also to lock the upper sash in raised position so that access can be had only by breaking the glass in the latter sash or in both sashes when the lower sash is raised.

My invention further contemplates adapting the guard to move vertically, in which event it is retracted int-o the wall space below the window frame, or to move horizontally, in which event it is retracted `into the wall space at the desired side ot the sash, and it is obvious that in'either form my invention is adapted for use with both sliding or easement windows.

The novel features ot my invention and its structural advantages can be better understoodby reference to the accompanying drawings which illustrate only the `preferred embodiments of my invention, and in whieh:-

Fig. 1 shows a vertically sliding guardin partial front elevation.

` Fig. 2 isa cross-sectional view taken on the line Q ot Fig. 1 with a lock which would not appear in this view in dotted linesI to show its relation with the other parts.

Fig. 3 is a view in section through the upper sash guide showing that sash and the guard in elevation in raised positions with the lock in front elevation.

Fig. l is a front elevation of a window with a laterally sliding guard shown locked in operating position.

Fig. 5 is an enlarged detail view ot a portion of the guard showing the lock in elevation and a portion of the guides tor the guard bars.

i Similar reference numerals refer to similar parts throughout the drawings.

In the embodiment ot my invention illustrated in Figs; 1 to 3, I show a window frame 1 which may be of ordinary construction for vertically slidable lower and upper sashes 2 and 3, respectively. The frame is 1923. Serial No. 644,261.

provided with the usual guide rails 4 forming guides 5 and t5, respectively, for the sashes and 3. l provide in the bottom sill of the sash traine, in line with the guide G lor the outer or upper sash, a series of openings S which are adapted to receive the vertical bars 9 forming the guard, which bars are connected at their top by a cross bar l0. There is also connected to this cross bar at each side a bar 11 which is fitted to slide in the sash guide (i in the same manner that the sash does, and suitable openings are provided for these side bars 11 in the bottom sill. ln one et the sidebars 1l I provide the notches l2 and 13 which open towards the sash guide 6 and are adapted to co-act with a spring .latch 14 which projects through the outer sash guide 6 nearthe upper end tl'iereof. This latch is of the springpressed retractable type in common use mounted in a barrel l5. The `latch is retracted against the action of its spring bar by any suitable key controlledlock mechf anism, such for instance, as the typical Yale lock 1li having a rotatable barrel With a suitahleretracting connection (not shown) to the spring latch. This lock mechanism is merely conventionally shown asv it may be ol any desired character and mounted in any desirednianner so long as it will serve to control the unlatching of theguard so that the latter can, when desired, be lowered.v

I provide the notches 12 in orderthat the guard may be locked in position suliieiently below its uppermost position to enable ythe upper sash to be lowered slightly for ven tilating` purposes, say about six inches. When the guard is not needed, the key controlled latch is retracted, and theguard is lowered onto the bottom sill 7 where itis concealed sutilciently not to affect the appearance olf' the window. When it is desired againito use the guard, it is raised until one or the other of the notches engages the latch lil, and 'in this position the guard is locked so as to close the lower halt of the Window opening so effectively as to protect the same, while preventing the upper sash being lowered. Thus to break and enter the glass in the upper sash must be broken.

` `terringito the construction illustrated in Figs, fl and l show the window trame 1 provided with a series oit late al openings 1.7 in the sash guide and through these openings pass the bars 9 and the side bar 11 oit the sash guard which in this construction are horizontally disposed. The lower side bar of' the guard resti and slides upon the sill 7 which in this construction is leftsolid. The cross connecting; bai` l0y ot the guard, when in operatingposition, is received in and lits snugly into the Jgfde G on the side olf the sash traine opposite that having the openings 17.

Tn Figs. 4 and 5 l show the customary studdiingi 181 in the wall and as a preti-rind arrangement I bore openings in the studdiingi aligvnineP with the openings i7' andl mount therein` suitable guides i9l for the guail'dl members 9 and l1.` These guidesV as illustrated are formed by sections of pip.- ing but they' may be rn-ade up and mounted iin any: suitable Way; rThe latch'notcli- 2t)v is pi-ovidfed in such position on the top bar ll that it will come opposite the latch 14 when the guard `is in closed position. Tn this arrangement the latch is disposedabove theguard and is pressedl downwardly by its spring into engagement with the top zguardinernber El. The hey controlled mechanism. for operating the lato-h is the saine as that already described. it is to be noted' that the Vsash guide on the side oi the fra-nre towards which the rail l() is ino-ved to retract it, is provid-ed 'with a cou'ntersunl recess Ql into which the rail l0 ino-ves and seat-sA with its outer tace' Hush with the undisturbed Wall o1 the guide. Thus the guard* itseli' 't'ornis part oi' the guide (5 for the upper sashas* it is loweredA and by this Ineans it is eilectuaifly concealed and housed so that its presence, when not in use, i's not observable.

To. utilize a guard ot this type it is only necessary' to grasp the guard bar it). by the finger gri-'ps 22; therein and slide it across the Win-dow ope-ningu-ntil the' latch lst snaps into the notchQO, in which position it holds. the guard so that it cannot4 be retracted and'V in such, posi-tion the guard holds the upper sash raised and acts as a protective means in the same manner as described in connectionl with the vertically sliding guard. :It is. to; be understood that lthe guards may be ot any sui-table shape and design. that shown being merely illustrative, and that the ing; position may be changed as desired.

Though 1 have described with great. particulaiilty the details of the einbodiinent of the invention herein shown, it is not to be construed that T ain limited thereto, as changes in arrangement and substitution ol equivalents may be inade by those skilled iuy the art without depart-ing' lronrthe- .invention as dei'ined in the appended ciaim-s.

Having thus described niy invention, what I claim as new and desire 5to secure by Let ters Patent, is I" l. lin combination with a sasl-1 traine hav# ing guides for its'upper and lower slidablie with a vertical bar at one side and horizontal bars attached thereto atene end and leit tree at the other end, and tubular guides mounted to open thro-ugh a sash `guide at one side and adaptedto receive said bal, there beine a countersunk recess in the sashu'ide to seat said vertical bar iiush with said sash guide;

2. The combination with a window lira-nie having' a1 sash Way provided Withn series 75 of openings and `nuides rioifdly mounted .in horizontal jninent with said 'way openings, of window Huard comprising a rigid iframe composed of horizontal rods, a vertisashes, of a guard co1-n}n-'ising arigid trarne 60 -ca-l connectingbar for one end oil saidl rods, the tree ends oft said'rods bling'- slid-l abiethrough said open-ings and guides, saiil rsh Way having a countersunk recess to receiife said vertical? bar, and key controlled means to lock said' frame in its operating 85 position. V The combination of elements as describedy in clair-n 2, in which the gru-ide for one of the rods is spaced inwardly from said way, and a key controlledI latch mechanism adapted Ato co-act with the bar between the sash way and its guide to lool; theguard in Y ogerating,T position.A i
